Abstract

The utility model relates to a three-wheeled pram, belonging to a toy pram for children. The utility model is characterized in that which is a three-wheeled pram whose cross beam length is adjustable; namely, the horizontal distance of a handlebar and a saddle is adjustable. The utility model is composed of a front wheel, the handlebar connected with the front wheel, a pair of rear wheels, the saddle connected with the rear wheels through a supporting seat and a front and a rear cross beams whose both ends are respectively fixed and sheathed on the handlebar and the saddle, wherein, the cross beams can relatively move and be positioned. The degree of comfort can not drop following with the increase of the age, when children rides the utility model.

Description

Toy tricycle

A kind of toy tricycle belongs to children toy car and makes the field.

Present toy tricycle is because the length of its crossbeam is certain and uncontrollable, thereby its comfort level by bike is tending towards along with the growth at child's age descending.

But the purpose of this utility model is to provide a kind of toy tricycle of crossbeam length manual adjustments.

Of the present utility model being characterised in that: it by front vehicle wheel, coupled handlebar, a pair of rear wheel, with its vehicle seat that links to each other through bearing and two ends respectively with handlebar, vehicle seat Joint but mutually the socket and the forward and backward crossbeam that can relatively move and locate forms, but the former screw thread or pin connection.

Use proof: since the horizontal range between its handlebar and the vehicle seat can be along with the variation of crossbeam length relative adjustment, thereby can make the comfort level of riding be unlikely influenced along with the growth at child's age.

In order in conjunction with the embodiments the utility model to be done more detailed describing below, now as follows employed accompanying drawing title of present specification and numbering brief introduction:

Fig. 1: the oblique view of crossbeam variable-length that the utility model proposes and toy tricycle that can be by pin location;

Fig. 2: forward and backward crossbeam slip socket and the longitudinal sectional view of the relative position of forward and backward crossbeam when locating with pin;

Fig. 3: the longitudinal sectional view of their relative positions when forward and backward crossbeam is threaded;

Embodiment:

Ask for an interview Fig. 1～3.Wherein: the 1st, handlebar, the 2nd, front vehicle wheel, the 3rd, vehicle seat, the 4th, bearing, 5 is two rear wheels, the 6th, front beam, the 7th, be enclosed within the rear cross beam outside the front beam 6, the 8th, pin, the 9th, nut can add packing ring 10 (down together) where necessary.

In Fig. 2, because front beam 6 slides in the rear cross beam 7 and slides, thereby caused crossbeam length, the variation of horizontal range between handlebar 1 and the vehicle seat 3 just, in case crossbeam be of convenient length and forward and backward crossbeam 6,7 on pin hole when aliging one by one mutually, fixed with regard to available pin 8, nut 9, this adjusting has level.

In Fig. 3, because front beam 6 is enclosed within rear cross beam 7 interior being threaded with it and spiral advancing, thereby caused the change of crossbeam length, this adjusting is stepless.

Forward and backward crossbeam 6,7 is connected with handlebar 1, vehicle seat 3 solid welderings respectively.

This shows, but its comfort level of riding of the toy tricycle of this crossbeam length manual adjustment can not be subjected to the influence of child's age growth, and can reduce parking space, the user also is convenient to buy, select and carry.
